On average, humans have a need to feel safe and part of a tribe. If you can convince yourself that your tribe is correct and that it is best to eat boiled eggs from the big end first and that the people who eat boiled eggs from the small end first are wrong, you will feel better about your place in the world. If you don't know if the big end or the little end is best you will feel uneasy with the world.

Obviously there are exceptions. Some people can objectively look at the situation and come to the conclusion that there are good reasons to start on both sides, and it really depends on your priorities. But those people are not part of the noise, it is the people who are desperate to feel part of a group who are the loudest.
